NL16 – ICL System Ten and 25 Mini-Computer to RS232 Asynchronous Serial Interface/Converter

1982 Tripple MCU MC68701 / MC68705U3S / MC68705P3S based design

This design permitted the ICL Mini-Computer to interface to RS232 Asynchronous Serial Devices.

Such devices included PC’s (with Video and Printer Emulation Software that I wrote), DEC LA120 Serial Terminals (Keyboard and Printer), and other devices. The serial devices could be connected locally, or remotely via modems over dialup or leased telecom lines.
